This study was undertaken to determine whether pressure pulses that propagate through the induction system of a port injected engine influence wall wetting occurring on the surfaces of the intake port. Water was used as the working fluid to eliminate the need for a special room and measures otherwise required to deal with fire hazards that would be present if gasoline were used. An extensive experimental apparatus was constructed that would permit the control of air flow, fuel pressure, throttle position and acoustic pressure pulse amplitude while allowing measurements to be made of wall wetting that occurs in the intake port. The mass of water collected from the intake port was recorded and analyzed to permit identification of the effects associated with varying pressure pulse amplitude and timing relative to injection pulse timing in the intake port. National Instrument's LabVIEW software was used to generate signals required for the fuel injector and speaker operation. The results obtained from the experimental approach used in this study indicated that the amount of wall wetting can be affected by the pressure pulses propagating through the induction system. It was concluded that further research in this area should be conducted with special regard to wall wetting and pressure pulse interactions.Dept. of Mechanical, Automotive, and Materials Engineering.
